Audio plug-in sidebar?

Hello everyone

I searched for pages but couldn’t find any answer.

I have Cubase Elements 8.0.35 (updated one). I was using Cubase 4 for years, didn’t use the newer versions because i used to it.

And now, I want to use the plug-ins like Autopan, Chorus, Compression, Delay etc. to audio channels.

In earlier versions, when I opened the recorded audio; at the left side, there were Edit, Select Process, Select Plug-in and History & Statistics sections but now, i can’t find or activate them.

Please can you help me with activating that sidebar if we can with this version of Cubase?
